摘 要:In a report on its joint mission with China to trace the origins of COVID-19,the World Health Organization(WHO)said it was"extremely unlikely"that the virus was released through a laboratory incident.Thirty-four experts from WHO and China conducted research in Wuhan for 28 days to conclude that the infection most probably spread through an intermediate host or through cold/food chain products.
